对无功资源的管理，特别是对输电运营商控制下的发电设施的管理，在维护电压稳定和系统可靠性方面起着重要作用。当前的反应性管理实践依赖于启发式方法和运营商的判断来获得反应性服务。因此，它缺乏透明的市场程序和采购成本最低的保证。本文提出了一种实用的、基于市场的解决方案，用于由输电运营商管理无功服务。该解决方案的三个显著特点是：(1)要求发电设施按照有功出力的比例提供无功服务；(2)优化和整合无功采购和市场运作，以获得最低成本的解决方案；(3)考虑有功和无功的相互作用，准确计算发电商失去的机会成本。建议的解决方案进一步简化了反应性管理的建模和结算方面。提出了一种无功管理的模型流程，供独立输电运营商参考。文中还给出了一个数值算例，说明了该方法的应用。
The management of reactive resources, in particular the generation facilities under control of transmission operators, plays an important role in maintaining voltage stability and system reliability. The current practice of reactive management relies on heuristics and operators' judgments to procure reactive services. Consequently, it lacks a transparent market process and assurance that the procurement costs are the lowest. This paper presents a practical, market-based solution for managing reactive services by transmission operators. Three distinct features for the proposed solution are: (1) obligating generation facilities to provide reactive services in proportion to their active power output; (2) optimizing and integrating the reactive procurement with market operation for least-cost solution; and (3) taking into account the interactions of active and reactive powers for accurate calculation of the lost opportunity costs of generators. The proposed solution further simplifies the modeling and settlement aspects of reactive management. A model process of reactive power management is presented for use by independent transmission operators. A numerical example is also given to illustrate the application of the proposed solution.
